Hello Hunter . The "SEF" [Symmetric Electro-Magnetic Field] Butterfly searchcoils are manufactured for Whites and Minelab Metal Detectors . They claim these new "SEF" coils are better and deeper than any concentric or DD search coil on the market , even better pin-pointing . Maybe someone on this Forum has used a "SEF" and would like to comment !!
HH......Regards.......Eugene
